Re: updatedn and refreshAndPersist in slapd.conf(5) in HEAD

No where in there is updatedn.

Yeah, it's still in HEAD slapd.conf(5) though.

Also in slapd.conf:

updatedn <dn> This option is only applicable in a slave database updated using slurpd(8). It specifies the DN permitted to update (subject to access controls) the replica (typically, this is the DN slurpd(8) binds to update the replica). Generally, this DN should not be the same as the rootdn used at the master.

The above isn't the latest slapd.conf(5), which doesn't talk about slurpd
